SUNNYVALE, Calif., April 20, 2026 (GLOBE NEWSWIRE) — BioCardia®, Inc. [Nasdaq: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today reported a positive outcome in its formal clinical consultation with Japan’s Pharmaceutical and Medical Device Agency (PMDA). PMDA has determined that the clinical safety and efficacy evidence for the CardiAMP® Cell Therapy in ischemic heart failure is likely sufficient to support market clearance. Good alignment was achieved in the meeting on the acceptability of the foreign clinical data that has been developed in the United States, the indications for use in patients, the approach for introduction of the therapy in Japan, and the need for continued post marketing studies in Japan. The Company will await the minutes from PMDA to provide detailed feedback and timeline for potential filing.   “We are thankful for PMDA’s engagement and for the unanimous support of the world class cardiologists from Japan and the United States attending the meeting,” said BioCardia Chief Executive Dr. Peter Altman. “We are on track to have the first minimally invasive biologic therapy in ischemic heart failure approved in Japan.” About CardiAMP Autologous Cell TherapyGranted FDA Breakthrough designation, CardiAMP Cell Therapy uses a patient’s own bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure intended to increase capillary density and reduce tissue fibrosis of myocardial tissue to address microvascular dysfunction. Clinical development of the CardiAMP Cell Therapy for heart failure is supported by the Maryland Stem Cell Research Fund and is reimbursed by Centers for Medicare and Medicaid Services (CMS). CAUTION – Limited by United States law to investigational use.  About BioCardia® BioCardia, Inc., headquartered in Sunnyvale, California, is a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary disease.

SUNNYVALE, Calif., Feb. 10, 2026 (GLOBE NEWSWIRE) — BioCardia, Inc. [Nasdaq: BCDA], a developer of cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today reported it has completed its Pre-Submission to FDA under its Q-Submission program for the approval of its Helix Transendocardial Delivery Catheter (“Helix”) for intramyocardial therapeutic and diagnostic agent delivery.    The data supporting safety and effectiveness for the Helix Pre-Submission is from fifteen well-controlled clinical trials of cell and gene therapy delivery to the heart using Helix, where patients were enrolled in three primary cardiac clinical indications. The Helix Pre Submission has been made under the CardiAMP Cell Therapy System FDA Breakthrough Designation, which the Helix underlies. BioCardia seeks to align with FDA on the regulatory pathway and timing for approval in the next 45 days. An application for market clearance could soon follow. “This Pre-Submission and discussion with FDA should lead to our Helix catheter being the first approved transendocardial delivery catheter system in the United States,” said Peter Altman, PhD, BioCardia’s President and CEO. “FDA clearance of Helix will streamline the future approvals of BioCardia’s autologous and allogeneic cell therapies for the treatment of Heart Failure and Chronic Myocardial Ischemia. Approval should also reduce development risk for biopharmaceutical and biotechnology partners seeking to employ our best-in-class minimally invasive delivery technology for cardiovascular cell, gene, and protein development programs aiming to address enormous unmet medical needs.”   About the Helix Transendocardial Delivery CatheterThe Helix transendocardial delivery catheter is an enabling platform for minimally invasive targeted delivery of therapeutic and diagnostic agents to the heart intramyocardially. It enables agents to be delivered precisely within the heart with superior retention over other therapeutic delivery modalities, and to many regions of the heart that other delivery methods cannot reach. The Helix includes a specialized small distal helical needle which engages the heart tissue from within the chamber of the heart and provides stability within the dynamic beating heart to safely enable agent delivery.  The Helix delivery catheter is intended to be used by interventional cardiologists, electrophysiologists, and cardiac surgeons trained to perform endovascular and transendocardial procedures. In independent reviews of clinical experience with Helix relative to other transendocardial delivery catheters, it has shown superior procedural safety1 and in pre-clinical studies has demonstrated a three-fold increase in effective dosing compared to open surgical access intramyocardial biotherapeutic delivery and eighteen-fold increase compared to intracoronary artery infusion2. The Helix catheter is further enhanced by BioCardia’s FDA approved Morph® DNA™ steerable introducer product, which physicians use to navigate the Helix with superior control in the heart. About BioCardia BioCardia, Inc., headquartered in Sunnyvale, California, is developing cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary disease. CardiAMP® autologous and CardiALLO™ allogeneic cell therapies are the Company’s biotherapeutic platforms with three cardiac clinical stage product candidates in development.

SUNNYVALE, Calif., Nov. 10, 2025 (GLOBE NEWSWIRE) — BioCardia, Inc. [NASDAQ: BCDA], a global leader in cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases, today announced the first patient enrolled at Henry Ford Health in its ongoing Phase 3 CardiAMP® HF II clinical trial for patients with ischemic heart failure of reduced ejection fraction (“HFrEF”). “The CardiAMP-HF trial, in which Henry Ford Health participated, was groundbreaking for the field of heart failure. Although the primary endpoint was not met, the study showed impressive results with an autologous cell therapy in patients with HFrEF, particularly those with elevated biomarkers of heart stress,” said Dr. Gerald Koenig, M.D., Director of the Cardiac Catheterization Laboratory at Henry Ford West Bloomfield Hospital and Director of Clinical Research in the Cardiac Catheterization Laboratory at Henry Ford Health System, and Principal Investigator in the Phase 3 CardiAMP HF II trial. “Our team is actively offering patients the opportunity to participate in this important confirmatory study intended to enhance microvascular function and improve patient outcomes, including quality of life.” “We greatly value our collaboration with Dr. Koenig and the world class Henry Ford Health team in the CardiAMP HF II Trial,” said Peter Altman, PhD, CEO of BioCardia. “Between the U.S. and the EU, there are roughly 2 million ischemic HFrEF patients with NYHA Class II and III symptoms. Many of these patients have a prognosis worse than many cancers and few remaining options. This places a terrible burden on patients, their families, and the healthcare system. We are excited by the CardiAMP HF results showing that our cell therapy system reduced both mortality and major adverse cardiac events, improved quality of life, and showed positive impacts to other study endpoints in patients with HFrEF. These results suggest that our investigational cell therapy could address important clinical needs.” About the CardiAMP Heart Failure II Study CardiAMP HF II is a 250-patient randomized multicenter procedure placebo-controlled study of the CardiAMP autologous cell therapy as a one-time treatment for patients with ischemic heart failure with reduced ejection fraction (HFrEF) on guideline directed medical therapy having elevated NTproBNP. The study is intended to confirm the safety and efficacy results in these patients observed in the CardiAMP HF study. The CardiAMP HF II study uses a similar three-tier composite primary outcome measure to the CardiAMP HF study consisting of all cause death, nonfatal major adverse cardiac events, and a validated quality of life measure. In CardiAMP HF, this composite efficacy endpoint was achieved with statistical significance in the patients with elevated NTproBNP who are the focus of the CardiAMP HF II study. Advances in this therapeutic approach for this trial include using the cell population analysis at screening to define treatment doses and improvements to the Helix system including the FDA approved Morph DNA steerable platform. About CardiAMP Autologous Cell Therapy Granted FDA Breakthrough designation, CardiAMP Cell Therapy uses a patient’s own bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure intended to increase capillary density and reduce tissue fibrosis, treating microvascular dysfunction.
